Phenomenological developments for event-by-event fluctuations of conserved charges
Volodymyr Vovchenko
A brief overview of the recent developments concerning theoretical description of event-by-event fluctuations in heavy-ion collisions is presented, with an emphasis on the role of…
Coalescence, the thermal model and multi-fragmentation: The energy and volume dependence of light nuclei production in heavy ion collisions
Paula Hillmann, Katharina Käfer, Jan Steinheimer +2
We present results of a phase space coalescence approach within the UrQMD transport and -hybrid model for a very wide range of beam energies from SIS to LHC. The coalescence model…
Solving the puzzle of high temperature light (anti)-nuclei production in ultra-relativistic heavy ion collisions
Tim Neidig, Kai Gallmeister, Carsten Greiner +2
The creation of loosely bound objects in heavy ion collisions, e.g. light clusters, near the phase transition temperature has bee…
The BEST framework for the search for the QCD critical point and the chiral magnetic effect
Xin An, Marcus Bluhm, Lipei Du +40
The Beam Energy Scan Theory (BEST) Collaboration was formed with the goal of providing a theoretical framework for analyzing data from the Beam Energy Scan (BES) program at the rel…
Constraining the hadronic spectrum and repulsive interactions in a hadron resonance gas via fluctuations of conserved charges
Jamie M. Karthein, Volker Koch, Claudia Ratti +1
We simultaneously incorporate two common extensions of the hadron resonance gas model, namely the addition of extra, unconfirmed resonances to the particle list and the excluded vo…
Proton number cumulants and correlation functions in Au-Au collisions at GeV from hydrodynamics
Volodymyr Vovchenko, Volker Koch, Chun Shen
We present a dynamical description of (anti)proton number fluctuations cumulants and correlation functions in central Au-Au collisions at GeV by utili…
Machine learning based approach to fluid dynamics
Kirill Taradiy, Kai Zhou, Jan Steinheimer +3
We study the applicability of a Deep Neural Network (DNN) approach to simulate one-dimensional non-relativistic fluid dynamics. Numerical fluid dynamical calculations are used to g…
Correcting event-by-event fluctuations in heavy-ion collisions for exact global conservation laws with the generalized subensemble acceptance method
Volodymyr Vovchenko
We introduce the subensemble acceptance method 2.0 (SAM-2.0) -- a procedure to correct cumulants of a random number distribution inside a subsystem for the effect of exact global c…
Constraining baryon annihilation in the hadronic phase of heavy-ion collisions via event-by-event fluctuations
Oleh Savchuk, Volodymyr Vovchenko, Volker Koch +2
We point out that the variance of net-baryon distribution normalized by the Skellam distribution baseline, , is sensitive to the possible m…
Ambiguities in the hadro-chemical freeze-out of Au+Au collisions at SIS18 energies and how to resolve them
Anton Motornenko, Jan Steinheimer, Volodymyr Vovchenko +2
The thermal fit to preliminary HADES data of Au+Au collisions at GeV shows two degenerate solutions at MeV and MeV. The analysis of…
Exploring the QCD phase diagram with fluctuations
Volker Koch, Volodymyr Vovchenko
We report on recent progress concerning theoretical description of event-by-event fluctuations in heavy-ion collisions. Specifically we discuss a new Cooper-Frye particlization rou…
Phase diagram of interacting pion matter and isospin charge fluctuations
O. S. Stashko, O. V. Savchuk, R. V. Poberezhnyuk +2
Equation of state and electric (isospin) charge fluctuations are studied for matter composed of interacting pions. The pion matter is described by self interacting scalar fields vi…
Efficiency corrections for factorial moments and cumulants of overlapping sets of particles
Volodymyr Vovchenko, Volker Koch
In this note we discuss subtleties associated with the efficiency corrections for measurements of off-diagonal cumulants and factorial moments for a situation when one deals with o…
